The royal visitors were attending the show, in Harrogate, as it enters its third and final day.

During the visit, the Queen and Prince Phillip were shown the event's many attractions, including the sheep and cattle breeders ring, riding demonstrations and a champion cattle parade.

Around 150,000 visitors are expected to attend this year's show at the 250-acre Great Yorkshire Showground.

It is the Queen's fourth visit to the show and her first since her Silver Jubilee in 1977.

The monarch was the Yorkshire Agricultural Society's patron between 1952 and 1998, when she handed over the role to the Prince of Wales.

Bill Cowling, honorary show director, said: "We are delighted that the Queen and the Duke of Edinburgh are visiting the Great Yorkshire Show, particularly during this, our 150th show.

"It is a great honour to welcome royal visitors to the showground and we look forward to the Queen seeing how the show has developed since her last trip to Harrogate."

The last royal visit to the Great Yorkshire Show was in 2006 when the Prince of Wales and the Duchess of Cornwall attended the event. 100955
